Watch 10 episodes of CBC News shows

If you search for a show titled Marketplace, and go to season 42, there should be an episode called “Orange Juice: Juicy Secrets (Preview),” which is sixteen seconds long. Watch this 10 times over and you got it.
The problem is that previews and promos tend to come and go, so if this is no longer around, you’re going to have to resort to watching 10 full 45-minute episodes. Last I checked, the preview was still there.
